Convert LNB to a very powerful antenna to receive remote WiFi networks

#wifi_free

Some points to consider. 1- Usb cable lenth should be less than 5 meters long otherwise, the signal will be lost. 2- The antenna wires should be 25 mm, about half 2.4ghz wave lenth(25mm ground and 25mm positive, 50mm in total). 3- For sure that with the corrects measures the dish will help a lot with signal strength.

People arent thinking right… Im an IT guy, who works on government networks, and this a GREAT idea! Very cool! Not sure why people are doubting this type of enginuity. It not only works better, at has completely changed the type of polarity from line of site to omni directional and has amplified as well. Good stuff, Sir!

my brother in armed force using this kind of device to intercept drone and satellite communications.

This reminds me of when we first had high speed and wifi as an option in my area. I used to do a lot of warchalking and built my own parabolic dish out of a mixing bowl and an external antenna. Great concept, and for those asking yes a FTA 39” dish would be better suited to capture the signal over a Dish or Directv style dish

[darrenwalter]

If you use the dish that it was originally used, it will narrow the area in space that it will listen and talk to while substantially amplifying the recieved signal and making the transmitted signal so concentrated that less signal will get lost in the ether, making it clearer and stronger to the receiver. Another result will be that the transmitted signal will be less likely to be found by other devices unless they are in the signal cone created by the lnb either directly in front of or directly behind the intended receiver. A downside is that nearly any object placed between the sender and receiver will block the signal, just like with the new 5g, but I have heard that someone has developed a technique to reduce the affect of things in-between the units. It's very convenient that wifi and satellite communication use ecactly the same frequencies, only the protocols vary. I would leave the lnb mounted on the dish and make the changes so that the alignment with the dish remains the same. There's no point to removing it except to waste time and cause yourself frustration trying to get it perfect again, unless you're not going to use the dish at all. I have seen folks do this with routers and switches with excellent results. Pretty much any device which has an antenna seperate from the device with a wire connecting them, and is wifi of course, is a good candidate for this modification.

I love how bonkers looks your projects at the beginning but at the end of video all makes sense.

Trimming the radiator length to resonance would help a bit. Online calculator tells me that is 29.7mm. I'll give it a try as I'm in a lousy low laying location.

New viewer, 2nd video. This is my tribe. I am home. Hey erbody 😊


Seriously tho, I’m geeking out on this content and am already committed to this binge. You sir, and people like you, are the real Einsteins and Hawkings far as I’m concerned. Thank You for putting all this out there for others.

[Rawezh-Kurdish]

if I use the original amplifire with some adapter to my computer ...is that mean we can connect to tesla internet???

What a load of rubbish an LNB isn't an antenna, the LNB horn is mounted at the focal point of the parabolic dish so that the RF signal coming from a specific direction will be reflected from anywhere on the dish face in phase constructively into the horn, if the signal is strong enough to receive just by pointing the LNB in the direction that the signal is coming from without using the dish then you don't need the LNB!

[deadlinerhorus]

LNB and USB-Stick from TP-Link both looks like an eroded mess. I'm not sure, if i would consider this a bold invention, by avoiding such crappy parts, from the beginning. And finally not glueing the usb-port will finally result in a broken device. Why so much effort while ending up in a mess of unprotected connectors?

[VladTN]

What is that jump drive everybody use? What it had be power wise to get best signal?

[mheuuj]

I cannot imagine the antenna being well matched to this tranceiver board.

[shanerorko]

That LNB looked matched for 9 to 12 ghz, using a 2.4ghz or even a 5ghz feed in that wave guide is not good at all.
Be better off making a dipole or biquad with a small reflector at 1.25 wavelengths.

[Jonnyweareten]

this wouldn't work well at all because the waveguide is designed for 10-12ghz not 2.4 or 5.8ghz

[jossmaxwell]

It would be nice if you talked us through what you are doing.

[pauljtonehead]

Active outdoor usb antennas are cheap now, work excellent! ( white rectangle with blue usb cord...the active wifi adapter is built into the antenna itself, outside. you just plug long blue usb cord into your computer)

[rogerwilco]

This may get you more signal, yet im not too sure if that translates to usable data and not just noise.

[abhimanyumonu]

useless video, fake info, u need atleast 5v and 3amp to power the adaptor after using extension of cable

[robertheintz]

Nice video. How do you know if the wire in the wave guide is cut to the right frequency?
